If you are looking for an amazing (memorable and special) 'off-the-beaten-track' / local experience in Bangkok, this is it. Far away from tourists (but not too far from great sights), Guang's place is nestled in a lovely bustling locals-only community with excellent 'authentic' markets close nearby (e.g. produce, clothing and food *note - make sure you get there between 6-9:30am or 6pm-10pm for amazing food).
Our room at Guang's place was quiet, stylish, spotlessly clean and incredibly comfortable - it surpassed my expectations (perhaps one of the nicest AirBnB rooms I have stayed in yet for the price). The place is not too far from many temples (both local and famous ones), and the 'special sites' to see. Grab a cheap TukTuk if you are not into walking, or walk it all (like we did - an awesome day's walk!).
Guang has excellent English, so he can help accommodate your interests accordingly. Guang kindly offered to accompany us for a night out - he showed us his favorite dinner spot at a local market (amazing), deciphered food stall items and shared many snacks with us, took a Tuk-Tuk with us to a special evening 'Flower market' where we purchased lotus flowers and jasmine flower leis (for the Buddhas), and finished off the evening in deep discussions while folding lotus flowers (for the Buddahs) with him and his brother. It was incredible to share knowledge about each of our cultures and learn from each other. I must also add another highlight was the amazing breakfasts that Guang's mother made - green curry and rice (incredible!!!) and a tasty rice noodle soup.
Our stay with Guang and his family was so memorable and special. We could not have asked for a better experience. Everything was absolutely perfect.
